BRAlDING-MACHINE.

QPECIPICATION forming part of Letters Patent No. 337,473, dated March 9,1886.

Application filed December .17, 1884. Serial No. 151,290. (No model.)

T at whom it may concern:

Be it known that I, JOHN ANDREW, of Birmingham, in the county of NewHaven and State of Connecticut, have invented an Improvement inBraiding-Machines, of which the following is a specification.

In braiding-machines of the nature shown in Figure 1, the puppets orspindles that carry the bobbin are directed in their courses through theracecircles formed of the slotted guideplates by turning shafts withprojections upon them termed winglets or directors. These winglets arebetween the upper and lower plates, and pivoted at their ends in re- 1cesses or holes in such plates. These winglets are turned to guide thepuppets, and they are subjected to sudden movements, and they are liableto rebound in cases where the speed is increased beyond an establishedrate.

If the winglet rebounds or partially turns, the puppet moving in onedirection isliable to be brought into collision with that going in theother direction.

My improvement is for holding the winglets in their proper positions,and at the same time allowing them to turn freely to direct the puppetsas they are moved along through the slotted plates known as therace-circles.

In the drawings, Fig. 1 is a sectional plan 0 of a portion of the lowerpart of a braidingmachine to which my invention is applicable, and Fig.2 is an elevation of my improved winglet, portions of the slottedguide-plates, together with the spring for the winglet, being shown insection in this figure.

The slotted guide-plates a and b are precisely alike, and the openingsin said plates are occupied by disks a upon vertical shafts I), (seeFig. 1,) supportedin any suitable manner. The shafts b aregearedtogether so that the adjoining disks a are-rotated in oppositedirections, as indicated by the arrows. Each disk a is made with twonotches in its edge upon opposite sides, of a size to receive the 4 5spindle f, carrying the bobbin, and. the duty of the winglets is todirect the passage of the spindles from disk to disk, so that they willtravel in their proper courses.

As braiding-machines of this character are well known, no furtherdescription of said ma- 5o chines is believed necessary. The winglet hasa the projecting guides 1 2 and the cam-arms 3 4, and at the ends of theconnecting-shaft are the pivots or arbors 5 6. These, all being ofordinary construction, do not require further description.

In the plate a are the holes or cylindrical recesses for the pivots 5 ofthe winglets; but instead of these holes being of a size to fit thepivots, I bore out each hole sufficiently large 6 to receive the helicalspring 1'. This spring is of a length greater than the length of thepivot 5, and of an internal diameter adapted to receive such pivot. Itwill now be understood that where the winglets, are introduced intoplace between the plates at b, with a spring, 1', around each pivot 5,such springs i will be slightly compressed and act cndwise upon thewinglet and produce a slight friction against the hub of the projectingguide 1 and of the hub of the guide 2 upon the plate 1); hence suchwinglets, although partially turned in the usual manner, will not be subject to any rebound or false motion in consequence of the inertia of thewinglet, and the speed of the machine can be greatly increased withoutrisk of the parts becoming misplaced. This friction-spring i occupiesbut little space. The machine does not have to be changed except toenlarge the holes for the pivots 5, and the Wear ofthe pivots is lessbecause the spring is similar to a loose bushing to the pivot; hence theefficiency and durability of the machine are augmented.

I claim as my invention- The combination, with the slotted guideplatesat b, the bobbin-spindles, the carriers a, and the winglets between saidplates, of a helical spring, 1', around one pivot of each winglet, therecess or hole for said pivot being en- 0 larged to receive the spring,as specified.

Signed by me this 22d day of December, A.

JOHN ANDREW.
